Patent AU-2002228860-A1 (AU)
Title: Ballast control ic with power factor correction
Inventor: RIBARICH THOMAS J
IPC: H05B41/24
Filed: 2001-10-19
Abstract: An integrated circuit with both ballast control and driver circuitry and power factor correction (PFC) control circuitry. At the beginning of preheating, power is provided to the load circuit at a voltage below a voltage at which the lamp can ignite, and the PFC control circuitry can then bring the DC bus voltage up to its running value. For this purpose, the PFC circuitry is enabled depending on the mode of the ballast control and driver circuitry. The DC bus voltage is regulated at a lower loop speed when the lamp is running than when the lamp is ramping to ignition, to alleviate DC bus droop. A criterion is applied to determine whether over-current detect signals indicate an actual fault. For this purpose, detect signals during ignition ramping can be counted and compared with a fault number. A lamp end-of-life condition can be detected by comparing sensed voltage with upper and lower window voltages. When a lamp is off for only a short time, it can be quickly restarted without full preheating.

Title: Method for radiation modification of oxide alumo-cobalto molybdenum catalysts for hydrodesulphurization
Inventor: PETROV LACHEZAR A
IPC: B01J37/34
Filed: 1991-05-21
Abstract: The method is applied in the chemical industry for increasing the activity and selectivity of oxide catalysts. Their activity persists even after repeated regeneration in an air flow 525 degrees C. It does not require the use of a special vacuum chamber or irradiation protection of the catalytic reactor, while any secondary radioactivity of treated materials is excluded. The method: the alumo-cobalt-molibdenum catalyst is irradiated with gamma rays at a total dose 100-1,000 kJ/kg at room temperature and atmospheric pressure. The irradiation is carried out prior to the reduction and sulphidisation, which are the processes necessary to set the catalysts in an operational mode.

Title: Pap smear inspection method and apparatus
Inventor: PETERS RICHARD K
IPC: G06T7/00
Filed: 1990-04-19
Abstract: ABSTRACT OF THE INVENTION  A pap smear inspection apparatus and method for automated screening of cytological smears for dense, possibly malignant cells.  A specimen slide is provided for receiving a cytological smear.  A microscope is provided for enlarging the image of the smear.  The microscope is further provided with a mechanical stage having the ability to be controlled by an external computer.  In addition, the microscope is outfitted to receive a video camera for creating an analog video signal corresponding to an area enlarged by the microscope and being observed by the video camera.  A video timer synchronizes operation of the smear analysis apparatus.  An image window generator focuses the analysis of the apparatus on a sub-area of the entire video image.  The size of the sub-area is adjusted to maximize recognition of cancerous cells.  A digital-to-analog converter is also provided for converting a digital threshold level into a corresponding analog threshold level, wherein both an upper and a lower threshold level may be produced for use.  A comparator is used for transforming the analog video input signal into a binary video signal (having only ON or OFF pixels) according to the analog threshold levels, wherein the gray level of the video input must fall between the lower threshold level and the upper threshold level for a pixel to be transformed into an ON state.  The thresholds are set so that the extra dense or irregular cells cause a sufficient number of pixels to be activated to facilitate recognition, but also so that normal cells activate few enough pixels that they will not be mistaken for irregular cells.   A  pixel counter sums the number of ON pixels both in the transformed video signal, and within the designated window sub-area of said video signal.  The counter further produces a digital count output (in binary numerical form) corresponding to the number of ON pixels.  A microprocessor compares said digital count output with a user-defined limit on the number of ON pixels allowed to occur within each sub-area under study, and if the limit is exceeded, the current area has failed the test for acceptability.  A computer program controls operation of the microprocessor, and typically includes computer code to sum the total number of cells present on a slide, as well as code to store and recall the X-Y coordinates of the failed areas of the slide to facilitate technician examination.
